[QUOTE="cwa107, post: 1480794, member: 24098"] I hate to say it, but I think the hard drive is the least of your worries if it doesn't even show a picture on the screen. Before you get too crazy, try doing a PRAM reset. Start with the machine turned off. Pull the power cord just to be sure you're doing this from a "cold" state. Plug it back in, turn it on and immediately press and hold Command + Option + P + R. Continue holding until you hear the startup chime twice. If no startup chime sounds, you may have a more significant problem (i.e. a bad logic board or power supply). [/QUOTE]
